Crescent Spring is the next stop on our tour of Eureka’s spring reservations, set aside for public benefit early in the city’s history. This is the one for which Crescent Hotel is named, and you can still climb the stone steps up the hill to see that stately castle in the Ozarks. The current gazebo replaced the original one many decades after it had fallen into disrepair, and for many years was white with sage green trim. The current purple-and-aqua color scheme was applied in 2013 during a renovation. It features a copper roof, which has acquired a natural patina.
